IMPROVED MACHINE FOR UPSET-TING TIRES.

The Schedule referred to'zinl these Letters Patent and making' part ofthe same.

To all whom it may concern:

Be it known that I, G. V. DALBE'Y, of Carrollton, in the county ofCarroll, and State of Mississippi, have invented a new and improved Tireand Band- Shrinker; and I. do hereby declare that the following is afnll, clear, and exact .descniption -thereoi`,.wvl1ich will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich- Fignre l represents a plan or' top view of my improved tire andband-shrinker.

Figure 2 is a side view of the same.

Figin'e 3 is an end view of the same.

Figure 4 is a vertical transverse section of the same, taken on theplane of the line :e x, fig. 2.v

Similar letters of reference indicate corresponding parts.

This in'vention relates to a new device for shrinking all kinds of tiresand bands; and consists of a novel arrangement and combination of parts,whereby both large, as well as small tires and bands, -ot all kinds, canbe shrunk to suitable-sized circles.

A, in the drawing, represents a wooden or other frame, of suitable size.

Upon it are fastened two plates or bars, B and C,"

of which one, B, is securely fastened to the frame, while the other ispivoted at its rear end by a-pin, a, to the frame.

The front ends of the bars B C are, by two pivoted links b`e, and by onelever D, which is pivoted to both links, connected with each other, asin iig. 3.

By swinging the lever D into a horizontal posit-lon, the front ends of Band C will he swung apart.

By raising it to a vertical position, they will be moved together. l

el d and d d are bolts, having eyes formed in their npfper ends, toreceive the fulcrum-pins e e ofthe levers E F. v

Said bolts have screw-threads cut upon their lower ends, to receivescrew-nuts, whereby the levers E F may be adjusted vertically, to allowlarger or smaller tires to be placed between them, and-thc plates f f infront or rear of the pins e..

The levers E F are hinged together at their rear ends, while their frontends may be separated or swung apart, the lever F being, for thatpurpose, secured by the bolts d, to a block, j, sliding in a slot in thecross-piece@ of .the bed A.

The lever E, as will be observed, is stationary upon said bar t'.

Upon the bars B C are placed transverse plates f f, with ronghenedsurfaces, in front and rear ofthe piv ots e, as shown. y f

On. the under sides of the levers lll F, opposite to the plates fj, arealso secured plates g g, with roughened lower faces.

The front ends of the levers E F are tapered to quite narrow points, andbent toward each other, to accommodate small rings.

' The movable bar C is held down upon the frame A by a clamp,h,.fastened to its, front end, and projecting over the 4edge of a plate,G, which is secured upon the iront cross-bar i of the frame A.

The plate G, as well as the cross-bar under it, are

slotted, to accommodate a head, j, that is suspended from the movablebar C, as shown in iig. 4.

The band to be shrunk, it" large, is placed npon the plates f, under thelevers E F, while the bars B C are apart, and is clamped by the levers EF; and then the lever D is swung up, to bring the clamped partstogether, thereby upsetting the band to the required degree.' lf theband is large, it is shrunk behind the pivots e; if small, in front ofthe same.

Having thus described my invention,

I claim as new,'aud lesire to secure by Letters Patent- 1. A tire andlbaml-shrinker, consisting of the bars B O, ofwhich one is pivoted, ofthe levers D E F, links b c, andclamping-plates j' g, all arranged andoperatingsubstantially as herein shown and described.

l2. The' levers E F, when pivoted together and to the bars B, as shown,whereby they are adapted to be swung n p, for the purpose of operatingas clamps, in'connection with the plates ff, set forth.

3. The levers E F, when tapered in front of their pivots e e, and curvedtoward each other, substantially as herein shown and described, to beaccommodated to small rings, as set forth..

4. The slotted plate G, when used as a guide, and

in combination with the clamp h, as a retainer for the movable bar C, asset forth.

The above specification of my invention signed by me, this'20th day ofMay, '1869.
